Kaby Lake Notebook Business

Alapvető. Manapság a notebook tömegterméknek számít, és a megfizethető üzleti notebookokból tizenkettő egy tucat. A tömegből kitűnni nem egyszerű, különösen, ha olyan márkák ellen küzd az ember, amelyeknek már megvan a saját helyük. Lássuk, vajon az Acer TravelMate 449 milyen esélyekkel indul az üzleti belépő szinten a ProBook-ok, Latitude-ok, és ThinkPad-ok ellen!

Not all notebooks can be opened 180 degrees.
The TravelMate's colors are business-like.
The case is made entirely out of plastic ...
... and the base is much more stable than the lid.
Overall, the P449 is fairly similar to the more expensive P648 ...
... from the positioning of the Acer logo ...
... to the exact same hinge design.
The bottom cover is equipped with two maintenance hatches.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
28 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 12 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 58 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (26.7 ms).
       Response Time 50% Grey to 80% Grey
39 ms ... rise ↗ and fall ↘ combined↗ 22 ms rise
↘ 17 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (42.8 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 25000 Hz70 % brightness setting

The display backlight flickers at 25000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 70 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 25000 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 57 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 6272 (minimum: 43 - maximum: 142900) Hz was measured.

A megfizethető üzleti notebookokat tartják a gyártók a notebook piac alapjának: nem éppen izgalmasak, de a forgalmuk jelentős részét adják. A riválisok legyőzése elég nehéz, és a legtöbb készüléknek nem is sikerül kitűnnie. Ez a helyzet a TravelMate P449-cel is: üzleti gép, de semmi különleges nincs benne.

A P449 nagyon jó touchpadja az egyik erénye. Egy középszerű, vagy rossz touchpad képes agyonvágni a felhasználói élményt, emiatt szimpatikus, hogy az utóbbi években a gyártók egyre nagyobb gondot fordítanak erre is. Azt figyelembe véve, hogy egyes cégek, mint a HP, még mindig gyatra TN panelekkel szerelik fel a gépeiket, a P449 IPS panelje egy határozott pozitívum. Az alacsony hőmérséklet, és a gyors PCIe-SSD is ilyen erény, utóbbival más gyártó azonos kategóriájú gépében nem találkoztunk.

Nem kiemelkedő, de nem is rossz. A TravelMate P449 egy többnyire átlagos, de viszonylag jól összerakott készülék.

Sajnos kompromisszumokat ebben az esetben is kellett kötnie a gyártónak: a gyors PCIe-SSD mellett a P449 csak egy nagyon lassú, és rosszul tervezett SD olvasót kapott. Emellett a billentyűzet kiosztása sem tetszett, azt meg végképp nem értettük, hogy miért van a P449-ben egy 2.5 inches meghajtónak hely, ha a szükséges csatlakozók viszont hiányoznak belőle. Az alapvetően mérsékelt melegedés pedig nem indokolná, hogy a ventilátor szinte mindig pörögjön. A szegmensben megszokott módon a kijelző színlefedettsége is eléggé gyatra. Az üzemidő sem éppen fényes, más készülékek ebben sokkal jobban teljesítenek.

Mindent egybevetve a TravelMate P449 egészen elfogadható, ha megszoktuk a billentyűzetét. Egyik versenytársa sem tökéletes, bár némelyiknek határozott előnyei vannak vele szemben (kivehető telep vagy éppen dedikált GPU).
